Summary
Carotenoid biosynthesis research is extensive in higher plants but limited in early land plants like liverworts. This study reviews carotenoid pathways in liverworts to clarify the evolutionary history of these genes in land plants.
Area of Science:
- Plant Biology
- Evolutionary Biology
- Biochemistry
Background:
- Carotenoid biosynthesis pathways and genes are well-studied in higher plants.
- Research on carotenoid biosynthesis in early land plants (liverworts, mosses, ferns) is scarce, leaving evolutionary history unclear.
- Marchia polymorpha, a primitive liverwort, serves as a model for bryophytes.
Purpose of the Study:
- To review carotenoid biosynthesis in liverworts.
- To discuss the functional evolution of carotenogenic genes.
- To elucidate the evolutionary history of carotenoid biosynthesis genes in land plants.
Main Methods:
- Literature review of carotenoid biosynthesis in liverworts.
- Comparative analysis of carotenogenic genes across land plant lineages.
- Phylogenetic analysis of gene families.
Main Results:
- Identified key genes and pathways involved in carotenoid biosynthesis in liverworts.
- Highlighted differences and similarities in carotenoid pathways between liverworts and higher plants.
- Provided insights into the early evolution of carotenoid biosynthesis in terrestrial flora.
Conclusions:
- Liverworts provide crucial insights into the early evolution of carotenoid biosynthesis in land plants.
- Understanding these early pathways is essential for reconstructing the complete evolutionary history of carotenoid genes.
- Further research on early land plants is needed to fully understand plant biochemical evolution.

Microbial membranes exhibit remarkable diversity in lipid composition, reflecting evolutionary adaptations to various environmental conditions. The three domains of life—Bacteria, Archaea, and Eukarya—synthesize membrane lipids through distinct biosynthetic pathways, leading to fundamental structural differences that impact membrane stability, function, and adaptability.Fatty Acid-Based Lipids in Bacteria and EukaryaBacteria and eukaryotes share a common fatty acid biosynthesis...

01:46The Calvin Benson Cycle
5.2K
Ribulose 1,5- bisphosphate carboxylase/oxygenase (RuBisCo) is a critical enzyme that catalyzes carbon dioxide assimilation during photosynthesis. However, it is an inefficient enzyme, having an extremely slow catalytic rate. A typical enzyme can process about a thousand molecules per second; however, RuBisCo fixes only around three-carbon dioxides per second. Photosynthetic cells compensate for this slow rate by synthesizing very high amounts of RuBisCo, making it the most abundant single...

47.5K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

441
Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which...

Biosynthesis in bacteria is a fundamental anabolic process that generates essential macromolecules, including proteins, nucleic acids, lipids, and polysaccharides. These macromolecules are critical for cellular growth, replication, and function. The process is tightly regulated and energetically linked to catabolic pathways to ensure optimal resource utilization.Biosynthetic pathways begin with precursor metabolites such as pyruvate, acetyl-CoA, and glucose-6-phosphate derived from glycolysis,...

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
